Viewing Volume Information

You can view descriptive information about your EBS volumes. For example, you can
view
information about all volumes in a specific region or view detailed information about
a single
volume, including its size, volume type, whether the volume is encrypted, which master
key was
used to encrypt the volume, and the specific instance to which the volume is attached.

You can get additional information about your EBS volumes, such as how much disk space
is available, from the operating system on the instance.
